MEETING: July 21, 2009 Consent AGENDA NO.: 37
SUBJECT: Introduce, waive the reading, and set August 25, 2009, at 10:30 a.m. to consider
adoption of an ordinance amending the Monterey County Code, Title 12,
Section 12.12.010, to establish a 45 m.p.h. speed limit on Laureles Grade from
Carmel Valley Road to a point 500 feet north of the centerline of Miramonte
Road, in Carmel Valley.
DEPARTMENT: RMA Public Works
RECOMMENDATION:
It is recommended that the Board of Supervisors introduce, waive the reading, and set
August 25, 2009, at 10:30 a.m. to consider adoption of an ordinance amending the Monterey
County Code, Title 12, Section 12.12.0 10, to establish a 45 m.p.h. speed limit on Laureles Grade
from Carmel Valley Road to a point 500 feet north of the centerline of Miramonte Road, in
Carmel Valley.
SUMMARY/DISCUSSION:
Several residents that live in the southern area of Laureles Grade near Carmel Valley Road have
requested a posted speed limit of less than 55 m.p.h. to address traffic safety. There is currently
no speed limit signing. The maximum speed limit for Laureles Grade is governed by Section
22349 of the California Vehicle Code which states the maximum speed limit for a two-lane
roadway is 55 m.p.h., and the basic speed law which states you can not drive any faster than
what is prudent and safe for conditions.
The area of concern is one mile in length, has four intersections, several driveways, and carries
approximately 6,300 vehicles per day. Due to trees, dirt embankments and one curve,
intersection sight distance is limited at some of the intersections and driveways.
The Department of Public Works prepared an Engineering and Traffic Survey to determine what
prima facie speed limit could be established and enforced by radar. The survey determined
45 m.p.h. is appropriate and enforceable from Carmel Valley Road to just north of Miramonte
Road, a distance of 0.67 miles. An additional radar survey was taken between Miramonte Road
and one mile north of Carmel Valley Road which supports the existing 55 m.p.h. maximum
speed limit.
OTHER AGENCY INVOLVEMENT:
County Counsel has approved the ordinance as to form. The California Highway Patrol concurs
with this recommendation.
FINANCING:
There is no financial impact to the General Fund. Traffic control devices are paid from the Road
Fund. The cost to install the necessary signing and pavement legends is estimated at $800.
There are sufficient funds available in the Road Fund Fund 002, Unit 8195) to finance this
work.

OTHER CONSIDERATIONS accident records, unexpected conditions, etc.)
COLLISION HISTORY:
Annual average daily traffic AADT) 6,300
Segment length is 0,67 miles
2-year collision rate 2007 2008) 1.62 collisions per million vehicle
miles MVM) for all collisions. Injury + Fatal collision rate 1.30
collisions per MVM.
Expected collision rate on similar State Highways is 1.71 for all collisions
and 0.862 for injury plus fatal.
UNUSUAL CONDITIONS: 8 percent grade and limited sight distance when exiting side roads.
SUPPORTING CONDITION MAP ATTACHED:
DISCUSSION:
Using the 85th percentile speed alone would set the speed limit at 50 m.p.h. Because of limited corner sight
distance at Los Robles Drive 220 feet looking right & 245 feet looking left) and at Miramonte Road 700 feet
looking right & 460 feet looking left), an 8 percent downgrade for southbound traffic, and a somewhat high
injury plus fatal collision rate, it is recommended the posted limit be reduced an additional 5 mph and be set at
45 m.p.h.
PROPOSED SPEED LIMIT: 45 MPH
